Swaybar bracket

[GUNS]

Well you got it, I am unsure, this is mostly why I would like to discuss about that, to make sure of the theoretical effect of a bigger in the front vs a bigger in the rear.

What I understood is that reducing body roll in the front would decrease understeer. But is that true? If yes, then if you have a lot of body roll and install a bigger front bar it should decrease understeer, all being equal. Am I wrong?

You and Oppenheimer are both correct. The rule of thumb is stiffer front = understeer, stiffer rear = oversteer. However, by limiting body roll, you are also increasing potential grip. So with that being said without driving the car yet, the front swaybar will allow a little more understeer at the limit of the front tires, but that limit will be higher. Again, I'm assuming the only reason you would want understeer in this application is because the car had a tendency to overtsteer without a front bar.
